    VS commodore Ute 355 manual
    hey guys thought I’d put up about my ute
    Got it as a blown up V6 auto with lsd
    Cleaned it up removed a heap of stuff including motor and trans
    Already had 304 and T5 gearbox from my old VN BT1
    Got the block machined to 40’ and line bored 2bolt studs with steel stud girdle. I did cam bearing oil mod getting Fed from the front bearing instead of the main bearing
    Clearances and preped the block myself
    Got the scat crank and hbeam rods srp forged Chev pistons and yellaterra ultralight flywheel balanced
    Assembled it all myself
    Vn Heads were ported by Tony knight and did a awsum job with 2.02 and 1.9 valves
    Running crane f288 solid cam
    Crane rockers and offset orifice lifters
    Standard jp oil pump ported and modded with external pickup in sump
    -12 valley and rockercover breathers to perterson catchcan

    Runs 11.5:1 comp on98ulp timing locked at 26deg (detuned for street)
    Holley hp 950carb
    Torque power duelplane high rise manifold with 1” spacer
    MSD dissy coil and ignition module

    Runs pwr radiator with BF single thermofan and shroud

    Made 509hp at 6800rpm at 32deg timing where it hit the msd limiter didn’t have modded oil system then and were having bad oil problems so canned it there
    I think with e85 some more timing and 7000 rpm should go close to 550hp

    T5 gearbox rebuilt with new synchros and bearings done my self

    exhaust is 1 3/4" tri y pacys with modded end into 2.5" outlets (larger than standard) with full twin 3" exhaust made by me x merg 2 stainless mufflers and 2 hotdog style mufflers with quad tips

    All good. I'm sure 2.02/1.6 is on the borderline for touching, although some go 2.05 or 2.08 intake I think. No way a 0.3" larger exh would fit (although anything is possible with TK magic) and not a likely upgrade unless you a smashing big boost (20-30 or more psi) down its throat.
    Loving the pictures too.

    Hang on, why the Holley hp 950carb?
    Do you not like EFI?

    I wanted to be able to tune it myself as no access to Dyno or tuner where I live at the time I built it they didn’t have any efi setups like Holley sniper and fitech ect
    I’m looking at putting the FiTech EFI 8 power adder 1200hp system and duel pump surge tank upto 1600hp so I can e85 and maybe nos down the track

    So ended up with a Holley super sniper 1250, 450 in tank pump, we just go a Dyno at work so that made it bit easier for tuning Made 370rwhp on e85 and 415rwhp with little shot of dry nitrous controlled by the Holley I thought I took a pic of it but can’t find it I’ll get one next time I’m on the Dyno computer. Took it to red centrenats my best time was 12.2 @ 115mph I think with a heap of 12.5s in the heat of the day. That’s with the t5 and 308 lsd diff and 245/60r17 nitto 555r tyres
    I tried once with the 245 19s and it spun 1st 2nd and 3rd to the 1/8mile on the nittos dead hooked unless I didn’t slip the clutch enuff off the line.
    Was crossing the line in 3rd gear at 6800rpm was good fun!
    Now I’m looking into dropping some comp a cam swap and a turbo pos rear mount looking for around 500rwhp and prolly going to a auto. Unles I can find a t56 cheap
